'In the Heights' and 'Hamilton' star Javier Muñoz recently revealed that he is battling cancer. The actor who serves as Lin-Manuel Miranda’s alternative and partner in creating the roles for both musicals has since had to scale down his involvement to only Sunday matinees in order to focus on his health. Now, Muñoz is making his diagnosis public and director Thomas Kail is discussing Muñoz future with the production.

Understudy Jon Rua recently got his shot at one of the most prized roles today, the titular 'Hamilton' in smash hit Broadway musical.. The General Charles Lee actor recently got the chance to take over for Lin-Manuel Miranda and Javier Munoz, who normally share the role with Munoz serving as alternate. Now Rua is opening up about the experience of a lifetime.

Lin-Manuel Miranda is getting his shot at superstardom. Miranda started his Broadway journey off hot with his debut musical, 'In the Heights,' which won two Tony Awards in 2008 as well as a 2009 Grammy Award. The writer/actor/composer then went on to provide the translations for the 2011 revival of 'West Side Story.' Miranda went on to provide the music and lyrics for the Broadway adaptation of Bring It On the Musical. Miranda has even won an Emmy Award for composing music at the 67th Tony Awards. That puts him one O away from the prized E.G.O.T. (Emmy, Grammy, Oscar, Tony). All of Miranda’s passion and drive has lead to his latest masterwork, 'Hamilton' which has taken Broadway and the world by storm. Now, it looks like Miranda might be taking a breath from 'Hamilton.' The very in demand actor is reportedly being looked at to co-star in the upcoming 'Mary Poppins' sequel, directed by Rob Marshall ('Into the Woods,' 'Chicago'). Have no fear. When, Miranda isn’t in the lead Javier Muñoz is stepping into Hamilton’s shoes.

Lin-Manuel Miranda's Broadway smash Hamilton has skyrocketed in ticket sales since the creator's visit to The Tonight Show -- and that has made Miranda quite tired. So on Sundays, Javier Munõz takes over the title role, and has been making a splash ever since.
